However，as environmental issues were becoming an eye － catching topic，the secondary pollution made by these methods was harder to be neglected. Besides，the methods of landfill and burning were introduced，a promising method of organic waste methanation was emphasized，by which organic waste was converted to biogas. According to the current research，compared with landfill or burning，the methanation method had the advantages including simpler process，less secondary pollution，as well as lower investment and operation cost. Further more，the methanation biogas was easily reprocessed by CO2 reforming of CH4 technology to convert into syngas. By this way，the recycling of urban organic waste would completely be hazard － free and resource. Therefore，the progress in CO2 reforming of CH4 by catalysis or plasma was reviewed also.Key words: urban household garbage; recycling; methanation; secondary polluti
